descri tion.

- My invention relates to: a rotary receiving neumatic ticketanddischarge. valve for distributing systems, and asfor its-object toprovide an .improvedand eflicient device which Will be reliable andcertain in operation and which willautomatically discharge 'tickets'deligvered into the valve-chamber tothe exterior thereofa a'Myinve'ntion contemplates arotary-val vecomprising a valve-chamber intowhich. a

ticket-delivering tube passes, the tube being arranged to deliver aticket between a pair" of o positelyrotating;rolls forming onewall of te chamber and adapted todischarge the ticket'to the exterior of thechamber. An exhaust-tube is connectedwith the chamber tube and force theticket theretl rougli into the valveechamber. I provide means for.-
